T at whom it may concern.-

.Be it known that I, GEORGE W. KING, of Marion, in the county of .Marion, State of Ohio, have-invented certain new and useful Improvements in Derricks and Excavators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to a portable derrick or excavator, and particularly to a combined locomotive, excavator, portable derrick, and wrecking-car.

The object is to make a portable machine that will be found very useful in loading iron ore, coal, and other material from stock-piles into cars; that can be used as a locomotive as Well as an excavator; that can be coupled onto a car, haul the latter to the stock-pile, dip or shovel up the material at one end of it, and swing the dipper or shovel to its other end and there dump or deposit the material into the car and then haul the laden car to the place desired; that can be readily con- Verted into a derrick by removing the dipper or shovel, and that can also be used as a wrecking-car.

With this object in view, and to the end of making a strong and durable machine, my invention consists in certain features of construction and combinations of parts hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure I is a side elevation, partly in section, of a ma chine embodying my invention. Fig. II is an end elevation of portions of the machine and shows particularly the boom-actuating drums, the hoisting-drums, and the machine-propel ling mechanism. Fig. III is a top plan in section on line III III, Fig. I.

Referring to the drawings, A designates the car-body or body portion of the machine,

' which car'body is provided at the bottom with wheeled axles a, whose two wheels ct are the distance apart required to enable the machine to run upon a standard-gage railway-track B. Oar-body A is provided with a suitably-operated engine or motor 12, and Z2 designates the engine-shaft, that is operatively provided with a pinion b meshing with a spur-gear b that is fixed upon a shaft 6 supported within and from and arranged horizontally and transversely of car-body A, centrally between the ends of the car and between the roof A and floor A of the car. Upon one end of shaft 19 is operatively mounted a sprocket-wheel 13 that is operatively connected by a chain 19 with asprocket-wheel If, that is operatively mounted upon a shaft b that is arranged horizontally and transversely above the carbody and supported from and below the carfloor A A double chain-pulley b is loosely mounted upon the central portion of shaft 19 A chain Z2 operatively connects pulley b with a chain-pulley a operatively mounted upon one of the axles below one end of the car-body. A chain b operatively connects the said pulley b with a chain-pulley a operatively mounted upon one of the axles below the other end of the car-body. A suitably-operated clutchb of any approved construction is employed for establishing and interrupting operative connection between pulley b and shaft 5 The machine is propelled upon track 13 When'the engine is in operation by establishing operativeconnection between pulley b and shaft 19 and is moved in the one direction or the other, according as the en gine-shaft is rotated in the one or the other direction. It is obvious, therefore, that'the machine thus far described forms a locomotive, and the oar-body A is preferably provided at each end with an ordinary car-coupler A Fig. I, for facilitating the coupling of the said locomotive to cars.

Upon the top or roofA of the car-body, centrally between the ends of the locomotive, is suitably mountedaperpendicular mast C,that consists, preferably, of a hollow cast-steel column. An annular turntable C encircles the lower end of the mast-forming column and extends over an annular horizontallyarranged shoulder 0', formed upon the base 0 of column 0. The column is rigidly secured to the car-body, and-antifriction devices-such, for instance, as balls g-are interposed between the opposing surfaces of the said base and the table. Column 0 gradually tapers toward its upper end and at said end is provided with a vertical bearing forming a hollow or vertically-perforated lug G A collar 0 is rotatably mounted upon the said lug C and rests upon an annular shoulder 0 at the lower end of saidlugor bearing. A boom D is supported from table O and the collar 0 The table 0 is preferably provided at the top with an annular flange O that encircles the column 0, and the boom that extends outwardly and upwardly from the table is suitably secured at its lower end to the said flange. The boom at its upper and outer end is connected by means of a rod D with collar 0 and the said rod is secured to the collar and boom in any approved manner. Collar O and table 0 have their axes coincident or in line vertically, and the.

said axes constitute the pivotal centers of the boom. The excavating-shovel d in Fig. I is supported from the boom in any wellknown manner, and in the case illustrated said shovel has an arm 61, provided with a rack (1 arranged longitudinally of the arm and meshing with apinion (1 that is operatively mounted upon a suitably-driven reversible shaft dflmounted upon the boom, and it is obvious that the shovel is thrust in or out, according as the said shaft is rotated in the one or the other direction. The shovel d has a bail 61 that is attached to the block or strap of the hoisting-tackle dflwhose sheave engages the fall d in the hoisting-cable (Z that is fixed at one end, as at d, to the booms outer end, thence leads downwardly to and in under the sheave of tackle d thence upwardly to and over a vertically-arranged sheave (Z supported from the booms outer end,thence iuwardly,over,and approximately parallel with rod D to and overa verticallyarranged sheave d, supported from collar O and thence downwardly through hollow bearing O and through the column 0 into car A, and leads'to and in under and operatively engages a winding-drum (Z called the hoisting-drum, that is loosely and slidably mounted upon the central portion of the shaft b as shown in Fig. II. A frictionclutch 01 (see Fig. II) is employed for establishingand interrupting operative connection between drum c1 and shaft 1)". One member of this clutch is formed upon the gear 19 and the companion clutch member is formed upon the drum. It is obvious, therefore, that the hoisting-cable is actuated in the direction required to lift the hoistingtackle by rendering the clutch operative and that the said tackle will lower by gravity upon rendering the clutch inoperative and permitting paying out of the said cable.

The location of the boom upon the roof of the car and the running of the hoisting-cable over a sheave located at the apex of the boom-carrying column or mast, it will be observed, accommodate a comparatively long stretch of chain between the said sheave and the drum, which stretch enables the twisting of the said cable a full turn without injuring the cable. Means for revolving or turning the mast and thereby enabling the boom to be swung to any point within a complete circle is provided and comprises, preferably,

two chains or cables O O fixed at O to the outer peripheral surface of table C. One cable 0 leads along the said peripheral surface of the table in the one direction and the other cable 0 leads along the said surface in the opposite direction. Each cable O leads to and from the table O to and over a horizontally-arranged guide-sheave O supported from the roof of car A near table 0. The two sheaves O O are located, preferably, a suitable distance apart at the same side of table 0. Each cable O leads from the engaging sheave C to and over a vertically-arranged guide sheave C supported from the said car-roof,and thence downwardly to and in under and operatively engages a winding-dru m O loosely mounted upon shaft 12 and a friction-clutch O for establishing and interrupting operative connection be-' tween the drum and the shaft is provided. One of the clutch members is rigid with the drum, and consequently loose upon the shaft, and the companion clutch member is fixed to the shaft. The two drums 0 called the swinging drums,are arranged at opposite ends, respectively, of and a suitable distance from the hoisting-drum d, and it is obvious that upon rendering the clutch for either of said drums O operative, while the clutch for the other drum 0 is inoperative, the boom will be swung laterally and rearwardly in one direction and that the boom is swung in the one or the other direction, according as the one or the other swinging drum is operatively connected with the shaft. Each cable 0 is fixed to table 0 preferably at a point diametrically opposite or approximately diametrically opposite the engaging sheave O.

In my improved machine hereinbefore described it will be observed that the booms sweep extends completely around the booms axis and the boom can be swung into any position radially of a circle whose is coincident with the booms axis, and consequently the hoisting-tackle can take up and deposit a load at any side of the booms axis, and the boom -swinging machinery and hoisting machinery and propelling machinery are carried directly by the car-body, that is made sufficiently strong for the purpose and has sufficient weight and strength to afford a substantial support for the derrick or boom-carrying mast. The heavy machinery is therefore not carried by the boom, and consequently does not have to be moved with the boom, and is located out of the way of the booins sweep. The machines body portion is preferably braced externally at the sides and at opposite sides of the elevated column by jacks or braces F, as shown in Figs. II and III.

My improved machine will be found useful not only in excavating, but in loading and transferring coal, ore, and other material at stock-piles and docks and at industrial plants engaged in the manufacture of iron and steel.

In the case illustrated in Fig. I the machine is coupled to a car J, that is upon track 13. In solid lines, Fig. I, the machine is shown taking up a load at one end of the car and in dotted lines is shown depositing a load into the said car J. In Fig. II the boom is swung into a position at right angles to the car-body A of the machine.
